Title: Proceso para preparar una composición aromatizante de aceite esencial de limeta destilado
Inventor: TAPANES PERAZA ROLANDO D
IPC: C11B9/02
Filed: 1975-12-30
Abstract: " Proceso para preparar una composición aromatizante de aceite esencial de limeta destilado" tiene como objetivo preparar una nueva composición del aceite esencial con una alta estabilidad y que mantiene el aroma del aceite natural. Ha sido comprobado que el principal causante del deterioro en el aroma del aceite natural es el p-cimeno producto de la descomposición del delta-terpineno que está presente en el aceite esencial. Nosotros hemos descubierto que casi todo el delta-terpineno y el p-cimeno pueden ser separados del aceite esencial de limeta destilado, primero por una destilación fraccionada a presión reducida bajo ciertas condiciones en presencia de agua, donde se separa la fracción de hidrocarburos monoterpénicos de los componentes oxigenados; y de esta fracción de hidrocarburos monoterpénicos el delta-terpineno y el p-cimeno pueden ser separados por otra destilación fraccionada a presión reducida en presencia de agua. Finalmente se mezcla los componentes oxigenados que quedaron como residuo de la primera destilación con el residuo de la segunda destilación para dar una composición aromatizante de aceite esencial de limeta destilado que posee estabilidad y mantiene el aroma del aceite natural.

Abstract: 1,107,925. Seaming non-metallic sheet material. ST. REGIS PAPER CO. 14 Oct., 1966 [21 Jan., 1966], No. 45965/66. Heading B5K. Two opposed sheet surfaces are continuously bonded together by progressively drawing together at a nip 16 the two surfaces having disposed between them an inflated tubular strand 24 of molten thermoplastic resin which is fed between the sheet surfaces in advance of the nip 16. As shown, two webs 10, 11 or a folded single web of sheet material, e.g. paper, are continuously advanced by pinch rollers 13, 14 defining the nip 16 and covered with resilient material, e.g. rubber. The bonded web is further advanced by rollers or other means (not shown). A roll 17 guides the edge of the web 10 so that the webs 10, 11 converge towards the nip 16 at a small acute angle, e.g. 10-15 degrees. The strand 24 is extruded from an annular channel in a die 18, Fig. 3, this channel being formed between a nozzle 20 and a flange 22 of a conduit 21 which supplies an inert non-flammable gas, e.g. air. The thickness of the strand 24 may be changed by using a different die having a nozzle 20 and/or a flange 22 of different dimensions or by replacing the flange 22 with another flange. The gas pressure is adjustable by a valve 23 so that the strand 24 is inflated to the desired size. Specified thermoplastic resins are polymers of olefins, e.g. ethylene and propylene, vinyl chloride, vinyl acetate and vinylidene chloride. copolymers of these monomers and a blend of these resins. The resins may contain a plasticizer. The invention is applicable to forming the side seams of bags.

Title: Improvements in or relating to means for driving the feed pump, draught blower and like auxiliary units in steam power systems
IPC: F01K13/00
Filed: 1933-01-03
Abstract: 412,962. Power-generating systems. SENTINEL WAGGON WORKS, Ltd., Iddesleigh House, Caxton Street, Tothill Street, London, and DOBLE, A., Alta Vista, Ridgebourne Road, Shrewsbury. Jan. 3, 1933, No. 187. [Classes 110 (iii) and 122 (iii).] In a steam power system described in connection with a road vehicle, an auxiliary steam engine or turbine 3 which may receive a portion or the whole of the main-engine exhaust and which drives the feed pump 9, draught blower 7 and other auxiliary units, is geared to the shaft of the main steam engine 2 by a unidirectional coupling 16 which is so arranged as to enable the shaft of the auxiliary engine to be driven by the shaft of the main engine or to overrun it so that it may be driven when the main engine is idle. The auxiliary units may be driven solely by the main engine or by the auxiliary engine, or by both. The engine 3 may be driven by steam from pipes 28, 29, 30. The pipe 29 is connected to the main-engine supply between the valve 26 and the engine 2. The pipe 28 is connected to an intermediate or low-pressure receiver or to the exhaust. Both pipes contain check valves 31, 32. A pipe 30 connected to the boiler may supply steam through a control valve 33. When the valve 33 is closed, the auxiliary steam supply depends upon the speed and/or load of the main engine. The engine 3 also operates a fan 5 arranged behind the condenser 4, an air pump 6, and a dynamo 10 which may function as a motor to drive the pump 9. A starting engine 8 is secured to the shaft of the blower, the drive from the engine 3 being effected through a free-wheel coupling 21. The compound or multiple-expansion engine 2 may be replaced by a single-expansion engine, the exhaust from which would pass directly to the engine 3, which in this case may be a turbine. The auxiliary exhaust 34 would lead directly to the condenser.

Title: Improvements in or relating to means for automatically adjusting or setting an oscillatory or vibratory system so that its natural frequency of vibration matches a predetermined frequency
Inventor: MILSOM FREDERICK ROGER
IPC: G04C11/00
Filed: 1949-01-04
Abstract: 664,413. Clocks and watches. SMITH & SONS (England), Ltd., S., and FURZEHILL LABORATORIES, Ltd. Jan. 4, 1950 [Jan. 4, 1949], No. 220/49. Class 139 [Also in Group XXXV] The frequency of oscillation of a balance wheel is controlled by applying forcing oscillations at the required frequency and comparing these with the phase or frequency of the resulting oscillation, any deviation causing a motor to adjust the effective length of the hair spring. The balance wheel 10 is oscillated by 2-phase induction motor coils 23, 24, fed from an oscillator 20, the input to coil 23 being modulated by a ring-bridge modulator 19 at the required wheel oscillation frequency, this being derived from a frequency standard 17. An oscillator 25 energises a pick-up coil 27 so that a signal modulated by the wheel frequency is induced in a second pick-up coil 28. A signal at the wheel frequency is obtained from this by comparison with the frequency of oscillator 25 in a ring-bridge demodulator 30. The wheel frequency signal is then applied to a further ring-bridge demodulator 34 to which is also applied via an adjustable phase shifter 35, the output of the frequency standard 17. If the balance wheel is not at resonance, then the two sets of oscillations are not in quadrature and a D.C. voltage of appropriate sign will be obtained from the demodulator 34, which, after amplification, operates the motor 16 to correctively move a pair of rollers along the hair spring. Whenever the balance wheel is removed from the mechanism, contacts 42 are opened and relay 40 is released to change over its contacts so that the outputs of the frequency standard 17 via amplifier 18 and via the phase shifter 35 are compared at 34. If these are not in quadrature the motor 37 effects the necessary correction. This ensures that the setting of the phase shifter is frequently checked. In a modification, Fig. 2 (not shown) the output of the frequency standard after frequency multiplication is fed to one synchronous motor, and the output of wheel frequency, after multiplication is fed to a second motor. The two motors are connected by a differential gear, the output of which adjusts the hair spring. In a further modification, the two motors and the differential are replaced by a pair of coaxial rotating field elements, one being free to rotate relative to the other and the relative rotation being used to adjust the hair spring. In another modification, Fig. 3 (not shown) the wheel frequency signal, after frequency multiplication, is applied to one phase winding of a two phase motor, and, via a tuned bridged-T network, to the other. Reference has been directed by the Comptroller to Specification 666,137.

Title: Machine for cutting off lengths from solid or hollow bars
IPC: B23B5/14
Filed: 1928-01-04
Abstract: 301,228. Taylor (Birmingham), Ltd., C., and Taylor, L. G. Jan. 4, 1928. Lathes.-In a cutting-off lathe comprising a rotary tool-head with radially-fed tools which are automatically retracted when the feed mechanism is stopped due to the disconnection of a clutch and application of a brake, the brake is of friction type and maintains the feed mechanism at rest, so that the tools are withdrawn against a positive stop, whereupon the head continues to rotate while the brake slips until it is automatically disengaged on connection of the feed clutch by hand to commence another cutting operation. The lathe comprises a bed 1 carrying a rotary tool head 4 and a non-rotary work-holder consisting of an adjustable jaw 21 and a screwed rod 22. The head is secured to a hollow spindle 12 which receives the work 20, and is rotated from a main drive shaft 2 through gearing 3. The tool slides 6 are fed by screwed spindles 11 rotated by worms 9, Fig. 2. and gears 8 from an annular wheel 7 rotatable on the spindle 12. A gear wheel 13, Fig. 1, keyed to the wheel 7, is driven at a slightly greater speed than the head for feeding the tools inwards, by a pinion 14 connected to the shaft 2 by a clutch 15 whose yoke 16 is actuated by a hand lever 17. A shaft 23 carries at one end a pinion 24 engaging the wheel 13, and at the other end a brake 25 consisting of a series of plates keyed to the shaft and interspaced by plates fixed to the casing 36, the plates being pressed together by a lever 38 pivoted to a sliding rod 19. Springs 40, 41 tend to apply the brake, but during cutting a lever 32 lies in the path of a collar 35 on the rod 19 to maintain the plates separated. In operation, the clutch 15 is engaged by the hand lever 17, and the brake 25 is released by the same action. The wheel 13 is then rotated slightly faster than the head 4 to feed the tools radially inwards until a clog 26, Fig. 2, adjustable in a slot 27 on one of the tool slides, engages a spring catch 30 pivoted to the head and causes the catch to trip the lever 32 and allow the springs 40, 41 to move the rod 19 to the left in Fig. 1, thus opening the clutch 15 and applying the brake 25. This causes the wheel 13 to remain stationary whilst the head rotates, and thus causes the tools to be retracted rapidly until a screwed stop 43, Fig. 2, on one or both of the tool slides engages a fixed stop 44 on the head by means of adjustable locknuts 45, and arrests the outward movement of the tools, the brake thereupon slipping until the hand lever 17 is again actuated.
